Scientists Make First Embryo Clones From Adults

Advancement Could Lead to Treatment for Alzheimer's, Heart Disease

Scientists in the U.S. have cloned two older people – one aged 35, the other 75 – into early-stage embryos, and then derived genetically-matched tissue through that process. Gautam Naik reports on Lunch Break. Photo: Young Jung

Scientists for the first time have cloned cells from two adults to create early-stage embryos, and then derived tissue from those embryos that perfectly matched the DNA of the donors.

The experiment represents another advance in the quest to make tissue in the laboratory that could treat a range of maladies, from heart attacks to Alzheimer's. The study, involving a 35-year-old man and one age 75, was published Thursday in the journal...
